A defective thermostat can result in engine overheating and potential internal damage. Improve the reliability of your 6.0L cooling system with a Mishimoto Ford 6.0L Powerstroke Low-Temperature Thermostat and CNC Housing! This thermostat is designed as a direct-fit replacement for your aged factory unit. The Mishimoto thermostat has a lower activation temperature (185 F) compared to the factory thermostat (192 F). The lower activation temperature allows coolant to flow through the engine earlier, which reduces and maintains lower engine temperatures. This thermostat is ideal for use in warmer climates or under extreme towing/driving conditions. The CNC machined 6061 aluminum housing will provide a proper seal and will not rust over time. Like all of our Powerstroke Performance parts, this thermostat and housing includes the Mishimoto Lifetime Warranty.Key FeaturesDirect fit for the 2003-2007 Ford 6.0L Powerstroke6061 CNC-machined aluminum housing includes pre-installed low-temperature thermostatLower activation temperature allows coolant to flow through the engine earlier, maintaining lower temperatures (Mishimoto thermostat activates at 185 F vs. factory 192 F)Ideal for vehicles in warm climates or under extreme towing/driving conditionsMishimoto Lifetime WarrantyPurchase Includes(1) Mishimoto Thermostat(1) Mishimoto CNC Thermostat Housing(1) Rubber O-Ring (for thermostat housing)Mishimoto Lifetime WarrantySpecificationsApplications2003-2007 F-250 6.0L Powerstroke2003-2007 F-350 6.0L Powerstroke2003-2007 F-450 6.0L Powerstroke2003-2007 F-550 6.0L PowerstrokeMishimoto Activation Temperature (F)185OEM Activation Temperature (F)192Note
